MACHINE FOR MAKING BASKET-COVERS.

SPECIFICATION forming part of Letters Patent N 0. 699,463, dated May 6, 1902.

Application filed October 31, 1901. Serial No. 80,648. (No model.)

To all whom it may concern.-

Be it known that I, CARL ENGBERG, a citizen of the United States, and a resident of St. Joseph, in the county of Berrien and State of Michigan, have invented a new and Improved Machine for Making Basket-Covers, of which the following is a full, clear, and exact description.

Thisinvention'relates to a machine for making covers for baskets and other receptacles, and it involves certain novel mechanism concerning the holder for the work and the means for rotating and otherwise actuating said holder as it coacts with the stapling or nailing device.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of the invention.' Fig. 2 is a front elevation with one of the work-holders in section. Fig. 3 is a vertical section taken along the drive-shaft of the machine. Fig. 4 is a horizontal section on the line 4 4 of Fig. 2. I Fig. 5 is a View of a cover made by the machine, and Fig. 6 is a sectional detail of the work-holder on the line 6 6 in Fig. 2.

6 indicates the base of the machine, on which are erected two stanchions 7, carrying rigidly at their upper ends a table 8. This table isprovided with two vertically-disposed bosses 9, carried rigidly thereby and through which the shafts 10, respectively, run. These shafts carry each a horizontally-disposed disk 11, forming part of the work-holder. this disl: having parallel ribs 12 thereon,which constitute guides for laying the parallel slats of the cover over the holder 11.

14E indicates catches for holding, in place the cross-slat which forms part of the cover, and 14 indicates a spring for holding the catch raised or lowered.

Fig. 5 shows the cover, and this comprises a rim or hoop 15, parallel slats 16, and a crossslat 17. The ribs 12 are separated to form a diametricallyextending passage across the top of the holder 11, in which the cross-slat 17 is received. Carried to slide radially on the underside of each form 11 are four clamps 18. (See Figs. 2 and 6.) These clamps have :rods 19 connected thereto, and the said rods are in turn joined to levers 20, fulcrumed on collars 23, fastened to the shafts 10. Sliding on each boss 9 is a cone 21, these cones working with the levers 20, which spread apart at the lowerends thereof when the cones are raised. This movement of the levers 20 will draw the clamps 18 inward and cause the hoop 15 of the cover (see Fig. 5) to be held firmly between the holder 11 and the clamps. The cones 21 are actuated by cranked shafts 6'5 22, which are rockably mounted in the table 8 and soarranged that by throwing upward the bent front portions of these cranked shafts 22 the cones 21 will be thrown upward and thelevers 20 actuated to clamp the hoops 7o 15 between the holders and the corresponding clamps 18.

56 indicates a retractile spring which is connected to the shafts 22, whereby to hold the cones 21 raised. The cones 21 may be either fast or loose on the bosses 9. If the cones are fast on the bosses, the levers 20 must turn around the cones during the action of the machine, as will be hereinafter fully de-- scribed; but if the cones are loose on the bosses 9 they may be connected with the parts 11 and23, so as to turn therewith.

The shafts 10 carry at their lower ends ratchet-wheels 24.,these wheels being fastened to the shafts, so as to impart a step-by-step rotary movement thereto.

25 indicates a double pawl which is carried on a shaft or rod 26 to move forward and back therewith. This rod 26 is mounted under the table 8 of the machine. The pawl 25 has c springs 27 connected thereto, and these springs are in turn attached to'arms 28, fastened to a lever 29, which is mounted fast on a hollow column or sleeve 30, carried to turn in avertioal tubular extension 31, preferably 5 formed integral with the table 8. The pawl 25 lies between the ratchet-wheels 24, and by throwing the lever 29 from one position to the other the pawl 25 may be made to engage either of the ratchet-wheels 24. This move- IOO ment of the lever 29 also turns the sleeve or column 30, for a purpose that will hereinafter appear. The shaft or rod 26 is mounted loosely in the framing of the machine just below the table 8 and is pressed backward by a spring 32. The rod 26 is moved forward through the action of an arm 33, against which works a cam 34, carriedto turn around the axis of the drive-shaft 35 of the machine. Now it will be clear that as the cam 34 works against the arm 33 it imparts, in conjunction with the spring 32, a reciprocal movement to the rod 26. This works the pawl back and forth, and one of the ratchet-wheels 24, according to which is engaged by the pawl 25, will be given a step-by-step rotation.

The cam 34 is carried on a sleeve 36, loosely encircling the shaft 35 and formed with a clutch member 37 and an eccentric 38. The clutch member 37 works with a clutch member 39, splined on the shaft 35, and the eccentric 38 has a strap 40 mounted thereon. The clutch member 39 is actuated by a bent and split lever 41, fulcrumed on a link 42, mounted on one of the stanchions 7 of the frame. This bent lever 41 projects through said stanchion at the front of the machine and is connected by a link 43 with the lever 29. Now it is clear that as this lever 29 is thrown horizontally from one side to another the link 43 will be actuated to throw the lever 41. When the lever 29 is in the intermediate position, (shown in Figs. 2 and 3,) the clutch member 39 will be disengaged from the member 37; but when the lever 29 is thrown to the right or left, as indicated by the dotted lines in Fig. 2, the bent lever 41 will be actuated to connect together the clutch members 39 and 37, thus turning with-the shaft 35 the parts 33, 36, and 34.

44 indicates two latches, which are mounted at the sides of the machine and are adapted to be engaged by the lever 29 to hold the lever either to the right or to the left, according as it maybe thrown. These latches 44 .have tails respectively extending adjacent to the peripheries of the ratchet-wheels24, and the ratchet-wheels have outwardly-projecting spurs 45, which as the ratchet-wheels turn run into engagement with the tails of the latches 44 and throw said latches into released position. Therefore when the lever .29 is thrown to one side it throws the pawl 25 into engagement with the ratchet-wheel 24, toward which the lever is thrown. It also connects the clutch members 37 and 39 and causes the cam 34 to turn with the shaft 35,

gages the latch 44 from the lever 29, and the lever then returns to its intermediate or inactive position.

In order to prevent idle movement of the ratchet-wheels 24, I provide friction-blocks 46-. (See Figs. 1 and 4.) These blocks 46 bear slidably on top of the ratchet-wheels and are carried, respective1y,by bent levers 47,mounted to rock in the rear stanchion 7 of the frame. The lower ends of the levers 47 are drawn tightly together by a retractile spring 48. The friction-blocks 46 being thus held on the ratchet-wheels 24 allow the ratchet-wheels such movement as may be imparted to them by the positive action of the pawl 25, but prevent the ratchet-wheels from moving by momentum or the jarring of the machine.

The hoop 15 and the slats 16 and 17 of the top being placed on the holder 11 in the proper position, as described, and the lever 29 thrown so as to cause the rotation of one of the holders, the staples are driven into the slats so as to fasten them to the hoop. The staples are driven by a stapling mechanism which maybe of any form desired. The drawings show the outline of this mechanism, 49 indicating the stationary part, which is carried on the sleeve or column 30, and 50 indicates the reciprocal part, which is carried loosely on a rod 51, arranged to slide through the sleeve 30 and connected by an arm 52 with the strap 40 of the eccentric 38.

55 indicates a spring which throws downward the rod 51.

54 indicates an arm carrying the wire-reel of the stapling device. As the lever 29 is thrown to adjust the pawl 25 it also turns the stapling mechanism, so that it will lie over the work-holder toward which the lever 29 is thrown. It will be seen that when the lever 29 is thrown to the right it starts the movement of the right-handholder. It also throws the stapling device to the right, and as the shaft 35 drives the eccentric 38 the movable part 50 of the stapling mechanism is operated, thus driving the staples through the slats into the hoop. The work is given a step-by-step movement, thus presenting it at various points around the periphery of the top or cover to the action of the stapling device. When the work has been given a complete turn, the projection 45 of the ratchet-wheel 24, which is rotating, will strike the corresponding latch 44 and throw the machine out of action. While one of the holders contains the work which is being operated on by the stapling device the attendant may be engaged in placing the Work in the other holder, and as the operation of the first holder ceases the attendant should throw the lever 29 toward the second-named holder, thus'starting the operation thereof.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claims.
